FOLDING UMBRELLA.

Specification of Letters Patent.

Patented Nov. 8, 1910.

To all whom it may concern:

Be it known that I, JOHN WILLIAM OLssoN, a subject of the King ofSweden, residing in New York city, county of New York, and State of NewYork, have invented a certain new and useful Improvement in FoldingUmbrellas; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

This invention relates to umbrellas and it consists in certainimprovements having for their principal object to provide an umbrella,parasol or the like which may be folded into such form that it may becarried in the pocket or in any other'limited space.

In the accompanying drawings, Figure 1 is a side elevation of sufficientof the frame of the improved umbrella to illustrate the invention; Fig.2 is a similar view showing the frame collapsed; Fig. 3 is a sideelevation, partly in section, showing the frame completely folded; Fig.4 is a side elevation showing the frame partly folded; Fig. 5 is a sideelevation of the staff as seen from the right in Fig. 1, the handlebeing removed; Fig. 6 is a side elevation of the staff and runner asseen from the left in Fig. 1, the staff being partly in section, thehandle removed and the runner appearing partly broken away. Figs. 7 and8 are detail views illustrating a joint in the stafi in its unbroken andbroken conditions, respectively;

Figs. 9, l0 and 11 are sectional views on lines ww, 00w and y-y of Fig.6. Fig. 12 is a sectional view on line z-z of Fig. 6, in which figurethe runner appears in dotted outline, partly depressed; Figs. 13 and 14are side elevations showing details of the handle; and, Fig. 15 is across-sectional view of one of the ribs.

The staff a is made in three sections, a, a and a the first of whichforms the handle. Section 0; is formed with a lever b which is pivotedbetween its ends so as to play in a slot 0 in the lower end of section awhich is tubular, the said slot extending higher at one side of sectiona than at the other (Fig. 5). Sections (4 and a are pivoted together bymeans of the angular link (Z (Figs. 5 to 8) which allows these sectionswhen folded to stand parallel to but somewhat spaced from each other(Fig. 3). The lower portion 6 of section a is half tubular, its portionf is tubular, its portion 9 is in the form of two parallel uprightsdiametrically opposite each other and its portion h is annular, thewhole being integrally formed. The uprights 9 have longitudinal ribs 9on the insides thereof and extending down into the tubular portion f andthese are received by the opposed notches i in a crown 7' which iscapable of movement vertically, guided by the ribs; to this crown arepivotally attached the ends of levers 70 (reference to which will beagain made) which form parts of the ribs. The crown is annular and it istraversed by a pin Z on which is pivoted the upper end of a link onwhose lower end is pivoted to a lever 11. fulcrumed at 0 in the tubularportionv f of the section a said portion being vertically slotted asshown to permit the lever to swing in the arc of a circle represented bythe dot-and-dash arc in Fig. 1. A link (comprising link-sections p, g)connects lever b with lever n. Now, upon folding the handle (the end ofits lever 12 following the path indicated by the dotted arc adjoiningthe pivot between the sections .a and a in Fig. 1), the crown will bedrawn down the staff, entering the tubular portion f of section (4 Thelink p-q is made in two sections pivoted together in the manner shown sothat, having drawn the crown down in the manner just described, it willfold when the sections a and a are folded, at which time the jointbetween the link-sections p, Q will be coincident with the jointsbetween the sections a and .54 The crown may carry the ferruled stem 9,which imparts a finish to the umbrella.

s is the runner, the same being an annulus with which the Spreaders tare pivotally connected in the usual manner; it has the radial loop 8,in which is pivoted the pawl a, reference to which will be again made.In collapsing the umbrella this runner has movement from the position inFig. 1 to that in Fig. 2; in folding the umbrella, it only has movementfrom the position in Fig. 1 to approximately the joint between sectionsa and a of the staff, as will appear. Along the flat face 6 of thehalftubular portion 6 of the section a of the staff is adapted to slidethe block '0 having a button '0 which enters a slot 6 in said flat facea and retains the block in place; this block is pivotally suspended fromthe lever n by the link if. The parts a, 2), q, m, a and j being in theposition shown in Fig. 1, the block 41 serves as a support for therunner in its upper position; to this end the pawl a has an upper tootha which, when the runner is elevated in raising the umbrella, will snapover the block Q) and support the runner; by pressing on the knob U2 ofthe pawl, it may be made to release the runner, so that the umbrella maybe collapsed. The pawl also has a tooth u which engages the block 41from beneath, so that when the block is lowered the runner will belowered with it, that is, in the folding of the umbrella.

Each rib comprises the sections to and w pivoted together so as to foldupon each other; the corresponding stretcher If is pivotally connectedto the rib-section 20 between its ends and somewhat nearer the innerthan the outer end thereof. The corresponding lever is has a fulcrum onrib-section to near the inner end of the latter, which is provided witha stop :0 limiting the unfolding movement of the lever and rib-sectionto past the position shown in Fig. 1. To the outer end of lever ispivoted one end of a link y which at its outer end is pivoted to theribsection w after the manner of a parallel rule, the link 3 having aU-shaped crosssection so that when the rib is extended (Fig. 1) the linkwill substantially sheathe the rib-section w (Fig. 15).

a designates the cover; this is attached in the usual manner to theouter ends of the rib-sections w, and at its center it is suitablyattached to the crown.

z is the usual spring catch for holding the runner down when theumbrella is collapsed.

The operations of collapsing and opening and folding and unfolding theumbrella are as follows: When the staff is extended block link p-q andtherefore causing lever it to turn on its fulcrum 0, the lever a,through link m, drawing down the crown j; in the downward movement oflever a, through link 4: the block 4) is depressed and since it isengaged with the runner s by means of the pawl 14 the runner is alsolowered. The lowering of the runner operates, through the stretchers t,partially to collapse the ribs,

and while this collapsing movement is progressing each lever is turns011 the rib-section to as a fulcrum and causes the link 3 to turn therib-section w upwardly on its pivot on rib-section w. The breaking ofthe joints between the rib-sections w and to may be assisted by pressingwith the hand against the under sides of the rib-sections w. Fig. 4shows the movements of the parts as above described as having proceededabout half way. Upon continuing to move the handle into folded relationwith staff-section 64 the runner will be depressed from lever a throughlink 0 while the crown is.

also being depressed from lever a through link m, the runner moving atthis time slightly faster than the crown owing to the relative positionsof link 12 with respect to the runner and lever n and link m withrespect to lever 71. and the crown. The result of this will be that eachrib-section w will be turned downwardly in Fig. 4 on its pivot on lever7c, link y acting to fold ribsection 10 against rib-section w as thelatter folds in to the staff. In the position of the parts at this timein the folding operation, the runner approximates the lower end of thestaff section a In the lowering of the crown the central part of thecover 2 is drawn within the annulus h (Fig. l). All that now remains tobe done is to fold staffsection a on staff-section a the angular link (Zallowing such spacing thereof as to accommodate the interposed parts is,t, Q0 y and w (Fig. 3). In unfolding the umbrella sections a and a arefirst arrangedin alinement with each other. Then the handle is turned onits pivot in section a to bring it in alinement with the latter. In thisoperation the link 0-g raises lever 'n, which, through parts 01 and m,raises the runner and crown and causes the extension of the ribs. Theoperation may be assisted by using the hand to bring the ribs into theirextended condition.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. In a folding umbrella, the combination of a stafi having a pivotedhandle portion, a lever pivoted in the upper part of the staff, a linkconnecting the lever and handle, a crown and a runner eachmovablelengthwise of the staff, means for transmitting movement from thelever to the crown, means for transmitting movement from the lever tothe runner, stretchers pivoted to the runner, levers pivoted to thecrown, folding ribs each comprising an inner and an outer sectionpivoted together and the inner sections being pivoted in the stretchersand affording fulcra for said levers, and links connecting the ends ofthe said levers with the outer rib-sections, substantially as described.
